$ qbs config profiles.<profile-name>.qbs.architecture x86
$ # ...
$ qbs build profile:<profile-name>

Or without a profile, but a direct command-line override instead:
$ qbs build modules.qbs.architecture:x86
(Although I admit I don't know 100% if the latter really works for project-level probes. Try it out.)

The blog post talks about Profile *items*, i.e. profiles that you instantiate within a project file. Those are much rarer than the "external" profiles created via qbs-config & friends.
